' Williamsburg, in the county of 'iClerment and State zof @hio,haredirvented certain new and useful Improvements in :Devices forClamping Patches 011 Tires,-of -wh1ch the following is a specificaticn.a

My inventlon relates to devices for clamping patches on tires and moreparticularly for clamping patches on inner tubes afar automobile tires.

lln repairing punctures in inner tubes it is very often diflicult toapply uniform pres sure to a patch after placing t over the puncturedportion of the tube in order to cause it to adhere properly to the tube.This difiiculty is particularly experienced when it is desired to repaira puncture whlle on the road, where it is the usual custom to apply thepressure on the patch with the hands or anything which might be handy"and adapted to answer the purpose.

It is well known that if the patch does not adhere properly at all ointsespecially around the edge it will wor itself loose, due toirregularities in the pressure while applying, and the tube will have tobe repaired again.

It is the object of my invention to provide a device to be usedwhenrepairing punctured tubes which will render it possible toapply'absolutely uniform pressure at all points on a patch applied to atube, and thereby insure that the patch will retain its I combinationsof parts as will proper pos1t1on.

llt is-a further, object of my inventlon. to construct a,device forapplying patches to tubes which-is simple in construction, inexpensiveto manufacture, and one which talres up littlespace and can be readilycarried about as part of the tube repalring outfit. My inventionconsists of certain parts and be described in the followingspecification and pointed out in the appended claim.

In the accompanying sheet of drawings which serves to illustrate myinvention:

Figure 1 is a plan view of my device in its open position showing aninner tube about to have a patch pressed thereon; Fig.- 2is anelevational view showing the tire in position just before the cam leveris operated to finish the clamping operation; Fig.

- 3 is a similar view showing the tire clamped in the device; and Fig. 4is a cross-sectional Viewv taken throughthe middle ofmy'device showingthe tube clamped I therein.

. :Referring-more particularly to the drawlngs 1 illustrates a lowerplate having apertures 2 and 3 therein through which .a=ten-- sion bar 4is adapted to pass. An upper plate '-5-1s provided which has apertures 2and therein through which the tension bar 4 is adapted to pass. Thetension bar 1 is provided with two perpendicular ends =6 @ancl'z'l whichpass through the apertures 2,

2", 3 and 3 thus allowing the plates to float perpendicularly withrelation to the tension ar and to each other. The perpendicular end 6 ofthe tension bar 4 is provided with a curved or turned up end 8 whichretains the plates on the tension bar. The other perpendicular end 7 ofthe tension bar is provided wlth a catch 9 which is adapted to springinto engagement withthe lower side of the plate 1 adjacent the aperture2. The tension bar is preferably constructed of spr ng'steel wire, whichallows the end 7 to sprlng slightly to properly engage the platel andforma spring catch as best illustrated 1n Fig. 4. Mounted on thehorizontal portion of the tension bar 4: I provide a cam lever 10 whichis adapted to rotate and slide freely on said tension bar. This camlever is provided with the cam 11, which is 1 asshown in Fig. 1. Thepatch 13 is then placed in position with the proper adhesive substancethereon and then the plate 5 is swung around using the perpendicular endportion 6 as a pivot. The perpendicular end portion 7 is then forceddown through the opening 2 in the plate 1 where it looks itself inposition. The cam lever which is in the position shown in Fig. 2 is thenoperated so that it assumes the position shown in Fig. 8, where it isseen that the tube is clasped tightly between the plates 1 and 5,thereby applying uniform pressure to the 1patch at every point. Afterthe device has een allowed to remain on the tube a sufficient length oftime for the patch to have thoroughly adhered to the tube, the cam leveris raised, thereby releasing the pressure of the plates on the tube andthe latch 9 on the end 7 of the tension bar is released allowing thetension bar and plate 5 tube Milt swung back, thereby allowing the tubeto be removed.

Thus it is seen that I produce a simple device which can be quicklyapplied to'a patched tube without having to ad]ust screws or bolts, andwith which pressure can be 7 applied almost instantaneously after thetube and plates are in proper position for applying the pressure bymeans of the cam lever 10.

Certain modifications of my invention can be made without departing fromits spirit and scope, and I do not wish to be confined to the exactdetails shown. Y

v What I claim as new and desire to secure by Letters Patent is a In adevice for clamping patches on tires, the combination with two pressingplates Y i 5 having apertures therein diametrically op posite eachother, a tension bar passing through the apertures on one side of theplates and bent to form a hinge to allow said plates to be moved inplanes parallel with each other, a downwardly extending portion on saidtension bar having a notch therein for engagement with the lower plate,said extension passing through the apertures in said plates opposite thehinge to lock said plates together, of means on said tension bar forforcing said plates together to press a tire therebetween, substantiallyasset forth.
